=====================  Hazards Identification  =====================

Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:YES    IARC:YES	  OSHA:NO
Health Hazards Acute and Chronic:CLASSIFIED AS A NUISANCE DUST BY OSHA,
    MSHA AND ACGIH. EXPOSURE CAN AFFECT THE SKIN, THE EYES AND MUCOUS
    MEMBRANES. THE PRODUCT CONTAINS SILICA PARTICLES THAT MAY BE BROKEN
    DOWN TO RESPIRABLE SIZE RAN GE DURING SHIPPING, HANDLING, OR USE,
    AND THUS MAY BE INHALED.  ACUTE EXPOSURE: CAN DRY THE SKIN AND
    CAUSE ALKALI BURNS. DUST CAN IRRITATE THE EYES AND UPPER
    RESPIRATORY SYSTEM. TOXIC EFFECTS NOTED IN	ANIMALS INCLUDE, FOR
    ACUTE EXPOSURE, ALVEOLAR DAMAGE WITH PULMONARY EDEMA. CHRONIC
    EXPOSURE: DUST CAN CAUSE INFLAMMATION OF THE LINING TISSUE OF THE
    INTERIOR OF THE NOSE AND INFLAMMATION OF THE CORNE A. (SIGNS AND
    SYMPTOMS OF OVEREXPOSURE)
Explanation of Carcinogenicity:CRYSTALLINE SILICA: IARC GROUP 1, VOLUME
    68, PAGE 41, 1997.	THE INTERNATIONAL AGENCY FOR RESEARCH ON CANCER
    (IARC) HAS EVALUATED IN VOLUME 42, MONOGRAPHS, SILICA AND SOME
    SILICATES (1987), THAT THERE  IS "SUFFICIENT EVIDENCE" FOR THE
    CARCINOGENICITY OF CRYSTALLINE SILICA TO EXPERIMENTAL ANIMALS AND
    "LIMITED EVIDENCE" WITH RESPECT TO HUMANS.
Effects of Overexposure:SYMPTOMS OF EXCESSIVE EXPOSURE INCLUDE
    SHORTNESS OF BREATH AND REDUCED PULMONARY FUNCTION. THIS INERT
    MATERIAL GIVES NO POTENTIAL ACUTE TOXIC HAZARD.	   HEALTH
    HAZARDS ACUTE AND CHRONIC (CONT): HY PERSENSITIVE INDIVIDUALS MAY
    DEVELOP AN ALLERGIC DERMATITIS. EXCESSIVE INHALATION OF SILICA DUST
    MAY RESULT IN RESPIRATORY DISEASE, INCLUDING SILICOSIS,
    PNEUMOCONIOSIS, PULMONARY FIBROSIS AND POSSIBLY  CANCER.
Medical Cond Aggravated by Exposure:INDIVIDUALS WITH SENSITIVE SKIN AND
    WITH PULMONARY AND/OR RESPIRATORY DISEASE, INCLUDING, BUT NOT
    LIMITED TO, ASTHMA AND BRONCHITIS, OR SUBJECT TO EYE IRRITATION,
    SHOULD BE PRECLUDED FROM EXPOSURE.

=======================  First Aid Measures  =======================

First Aid:EYES: IRRIGATE (FLOOD) EYES IMMEDIATELY AND REPEATEDLY WITH
    CLEAN WATER. SKIN: WASH EXPOSED SKIN WITH SOAP AND WATER. APPLY
    STERILE DRESSINGS. FOR GROSS INHALATION: REMOVE PERSON IMMEDIATELY
    TO FRESH  AIR, GIVE ARTIFICIAL RESPIRATION AS NEEDED. GET PROMP
    MEDICAL ATTENTION. INGESTION: CONTACT A PHYSICIAN IMMEDIATELY .

=====================  Fire Fighting Measures  =====================

Flash Point:NONCOMBUSTIBLE.
Extinguishing Media:MEDIA SUITABLE FOR SURROUNDING FIRE .
Fire Fighting Procedures:FIREFIGHTERS SHOULD WEAR NIOSH APPROVED
    SELF-CONTAINED BREATHING APPARATUS AND FULL PROTECTIVE EQUIPMENT .
Unusual Fire/Explosion Hazard:NONCOMBUSTIBLE AND NOT EXPLOSIVE.

==================  Accidental Release Measures  ==================

Spill Release Procedures:IF SPILLED, USE DUSTLESS METHODS (VACUUM) AND
    PLACE INTO CLOSABLE CONTAINER FOR DISPOSAL OR USE IF NOT
    CONTAMINATED OR WET.

======================	Handling and Storage  ======================

Handling and Storage Precautions:USE ADEQUATE VENTILATION. KEEP DRY
    UNTIL USED TO PRESERVE PRODUCT UTILITY.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:IN DUSTY ENVIRONMENTS, THE USE OF A NIOSH
    APPROVED RESPIRATOR IS RECOMMENDED.
Ventilation:LOCAL EXHAUST CAN BE USED, IF NECESSARY, TO CONTROL
    AIRBORNE DUST LEVELS.
Protective Gloves:IMPERVIOUS GLOVES.
Eye Protection:ANSI APPROVED SAFETY GLASSES . TIGHT FITTING GOGGLES IN
    DUSTY ENVIRONMENT
Other Protective Equipment:EYEWASH AND DELUGE SHOWER MEETING ANSI
    DESIGN CRITERIA . THE USE OF BARRIER CREAMS, BOOTS AND CLOTHING TO
    PROTECT THE SKIN FROM CONTACT IS RECOMMENDED.
Work Hygienic Practices:FOLLOWING WORK, WORKERS SHOULD SHOWER WITH SOAP
    AND WATER. PRECAUTIONS MUST BE OBSERVED BECAUSE BURNS OCCUR WITH
    LITTLE WARNING - LITTLE HEAT IS SENSED.
Supplemental Safety and Health
NIOSH HAS RECOMMENDED THAT THE PERMISSIBLE EXPOSURE LIMIT BE CHANGED TO
    50 MICROGRAMS RESPIRABLE FREE SILICA PER CUBIC METER OF AIR (50
    UG/M) AVERAGED OVER A WORK SHIFT OF UP TO 10 HOURS PER DAY, 40 H
    OURS PER WEEK. THE NIOSH CRITERIA DOCUMENT FOR CRYSTALLINE SILICA
    SHOULD BE CONSULTED FOR MORE DETAILED INFORMATION.
